Switch to composer mode in running instance

问题

How can I switch an existing project easily to composer? This project is updated from 6.1 to 8.7 now and should run in composer. A fresh composer setup is not a problem. For the last project I created a new host, installed TYPO3 via composer, installed the extensions via composer and migrated the db, fileadmin and uploads. Is there an easier way?

回答1:

Migrating TYPO3 from Classic Mode to Composer Mode requires at least the following steps:

Write down the current version of TYPO3 and all extensions
Remove all embedded TYPO3 and extension code incl. Git submodules
Add a Composer manifest
Add the Composer vendor-dir (and bin-dir if custom) to your .gitignore
Require TYPO3 and all extensions with the versions and --prefer-lowest, e.g.
```
composer require typo3/cms:^8.7.7 --prefer-lowest
```
This ensures that you don't accidentally perform updates before completing the switch.

Since no further changes to user files or database data is required you will be running TYPO3 in Composer Mode now.

Afterward you will most likely also need to adapt your deployment workflow to ensure at least one composer install is executed after deploying a new version.

There is no real other way, at least no automatic way, as you also upgrade maybe to newer versions or sometimes to the exact same version

回答3:

This is now documented in the "Installation and Upgrade Guide": https://docs.typo3.org/m/typo3/guide-installation/master/en-us/MigrateToComposer/Index.html

The steps are already outlined in the accepted answer.

As an alternative, you might want to create an installation from scratch with Composer and then use the generated composer.json for your system.
